New model on Windy: ICON vs. COSMO-EU vs. COSMO-DE

Hi all Meteorologists here

We are about to add new forecast model to Windy and we are currently deciding which one of these: ICON, COSMO-EU or COSMO-DE could have biggest quality advantage over ECMWF (do not worry, we do not plan to remove ECMWF).

Since we are serving million of users, our backend systems are scaled for maximum performance. Therefore adding new model in no easy and we must consider all the aspects (including limited space of User Interface) associated with it.

If there is someone, who is heavy user of these three models, please give us a hint, which one should be implement as the first one.

a) My area of interest is Europe.
b) Is a non-hydrostatic model (ECMWF is hydrostatic), with a small grid 97 km) and includes a detailed landscape. Is good for local phenomena (land / sea breeze, channelling of the wind in valleys, local rains due to mountains).
c) The prognostic variables provided in 1 hour timestep (up to 3 days).
d) COSMO-DE is very high resolution model (2.8 km grid) but includes only the area of Germany.
e) ICON is a global model, but ... if you have a Ferrari (ECMWF) you don't need a Porsche !

And there icon and icon EU are different data sets (with different update intervals)

And, as you can see, the WAM global and Europe Models are included now (bottom of document), don't know exactly what this is but it seems to include forecast about waves and swell, interesting for water sport I think
